Detail:
  Last revision broke _ll_mullu (the runtime support function for multiplying
  a 64-bit integer by an unsigned 32-bit integer) except for ROM builds that
  target CPUs with the M extension. So in practice, IOMD ROMs and softloadable
  C libraries both exhibited the bug.
Admin:
  Verified that the compiler will now run against this C library (previously
  it reported many non-sensical errors).

Version 5.63. Tagged as 'RISC_OSLib-5_63'
